  3. SW • ROOT v5-24-00a • ROOT v5-25-02 in preparation • AliRoot v4-17-Release • deployed to AFS and enabled via meta par-files containing no source code • AF-v4-17.par (loads VMC, Net, Tree, Physics, STEERBase, ANALYSIS, ESD, AOD, ANALYSISalice) • AF-v4-17-rec.par (enables the full AliRoot) • New features • Direct access to Grid files (read/write) • Raw reconstruction (see Cvetan’s talk) How to use CAF at http://aliceinfo.cern.ch/Offline/Activities/Analysis/CAF/index.html

  4. HW • Very few interventions on the CAF machines over the last 4 months • 30 more machines in two batches of 15 • one by end November • one by beginning of next year with similar configuration

  5. CAF Usage • Up to 21 users in parallel • Not assigned users will be refused access to CAF in the future • They receive an email every hour • CAF user ’foo' running in group 'default' • Number of groups: 20 • Number of unique users: 154(a user can belong to several groups)

  7. CPU Usage • CAF usage is significantly increased • Group default is not any more the most relevant Average CPU Usage = 4.2% Average CPU Usage = 4.8% 9 months, 2.47x109 secs CPUtime=1.03x108 secs 4 months, 1.1x109 secs CPUtime=0.53x108 secs

  8. Overview • CAF • Reached a proved stability, few reboots • Current SW suite includes ROOT v5/24-00a + AliRoot v4-17-Release • User support • Monthly tutorials at CERN, ~700 people attended so far • Mailing list: alice-project-analysis-task-force@cern.ch • Web page: http://aliceinfo.cern.ch/Offline/Analysis/CAF • Under development • Top hits in Gerri’s talk • Regular biweekly meeting among CAF/PROOF/Grid experts
